Window balance

Thank you very much for your offer to help. I've included two pictures one of the balance springs that I've taken off the window that were broken there's a single screw that attaches them to the window channel and the slide in the slot on the lower half. It looks like a double coiled spring from one of the attaching at the bottom and the top. The second picture is an identifying tag that I found on the bottom of the upper sash. It's a DR Horton home and that's the only identifiers that I could find. I don't know if that helps you identify it or not. Greatly appreciate any help that I can get thank you.

Looked to me like two coils connected to each other in the middle.
I checked both coils. I even removed them both. No stamp.

The sash weighs 19.8 lbs. Can you send a list of the parts I will need to completely rebuild both balances. Thank you Sooooo much
